[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] Reference Fig.12 and Fig.13As shown, the air-conditioning indoor unit 1000 of an embodiment of the utility model is shown. The air-conditioning indoor unit 1000 may be a wall-mounted air-conditioning indoor unit or a cabinet-type air-conditioning indoor unit. The following embodiments are mainly described by taking the wall-mounted air-conditioning indoor unit as an example.

[0041] Reference Figure 1 , Fig.12 and Fig.13 As shown, the air-conditioning indoor unit 1000 includes a shell component 100 and an air guide component 200. The shell component 100 is provided with an air outlet 110, and the air outlet 110 extends in the left-right direction. The air guide component 200 is arranged at the air outlet 110, and the air guide component 200 extends along the length direction of the air outlet 110. The airflow entering the air outlet 110 is first guided by the air guide component 200 and then flows out from the air guide component 200. The air guide component 200 can close or open the air outlet 110. The air guide component 200 can also change the flow direction of the airflow flowing out of the air outlet 110, that is, change the air outlet direction of the air outlet 110 to achieve air guiding to a specific position. The air conditioner indoor unit 1000 also includes a heat exchange component 300 and a fan component 400, both of which are arranged in the shell component 100. The heat exchange component 300 can exchange heat for the airflow inhaled by the fan component 400. The airflow inhaled by the fan component 400 passes through the heat exchange component 300 and then flows out from the air outlet 110, which can increase or decrease the temperature of the airflow to achieve the function of cooling or heating.

[0042] Specifically, refer to Figure 1 and Fig.12 As shown, the air guide assembly 200 includes a first air guide plate 210 and a second air guide plate 220 that can rotate relative to the shell assembly 100. The first air guide plate 210 is rotationally connected to the shell assembly 100, and the second air guide plate 220 is also rotationally connected to the shell assembly 100. The first air guide plate 210 and the second air guide plate 220 are rotationally connected, and the rotation axis of the first air guide plate 210 is set along the length direction of the air guide assembly 200, and the rotation axis of the second air guide plate 220 is also set along the length direction of the air guide assembly 200.

[0043] Specifically, the first air guide plate 210 and the second air guide plate 220 can rotate simultaneously. The first air guide plate 210 is located at the air outlet 110, and the second air guide plate 220 is also located at the air outlet 110. The first air guide plate 210 and the second air guide plate 220 can control the air outlet volume and air outlet direction of the air outlet 110. Specifically, the air outlet volume of the air outlet 110 is determined by the size of the opening formed between the first air guide plate 210 and the second air guide plate 220, and the air outlet direction of the air outlet 110 is determined by the rotation angle of the first air guide plate 210 relative to the second air guide plate 220. The first air guide plate 210 and the second air guide plate 220 can guide air forward, downward, front upper or front lower.

[0044] by Fig.12 Taking the arrow direction in FIG. 2 as an example, the first air guide plate 210 extends in the left-right direction, and the second air guide plate 220 also extends in the left-right direction. Figure 1 According to the direction of the arrows in the figure, the length direction of the first air guide plate 210 and the second air guide plate 220 is the left-right direction, and the rotation axis of the first air guide plate 210 and the rotation axis of the second air guide plate 220 can be parallel to each other. It can be understood that the rotation axis of the first air guide plate 210 is set along the left-right direction, and the rotation axis of the second air guide plate 220 is also set along the left-right direction. It can also be understood that the first air guide plate 210 and the second air guide plate 220 can swing downward or upward.

[0045] It is understandable that the first air guide plate 210 and the second air guide plate 220 may be rotatably connected to the housing assembly 100 via a rotating shaft and an axial hole structure, or may be rotatably connected via other common hinge structures.

[0046] Reference Figure 1 , Figure 3 and Fig.12 As shown, the air conditioner indoor unit 1000 is in the off state, the first air guide plate 210 and the second air guide plate 220 are in the initial position, and when the first air guide plate 210 and the second air guide plate 220 are close to each other, the first air guide plate 210 and the second air guide plate 220 completely cover the air outlet 110 to prevent external dust from entering the interior of the air conditioner indoor unit 1000. Fig.13 As shown, the air-conditioning indoor unit 1000 is in the on state. When the first air guide plate 210 and the second air guide plate 220 are rotated to a specific position, the first air guide plate 210 and the second air guide plate 220 open the air outlet 110 and guide the air flow at the air outlet 110 to achieve up and down sweeping. It can be understood that the first air guide plate 210 and the second air guide plate 220 are mainly used to control the deflection angle of the air flow at the air outlet 110 relative to the horizontal plane.

[0047] In some embodiments, a single driving device may be arranged to drive the first air guide plate 210 and the second air guide plate 220 to rotate simultaneously. For example, the driving device may be a motor, and the motor may drive the first air guide plate 210 and the second air guide plate 220 to rotate simultaneously through a transmission mechanism of a planetary gear. Specifically, the transmission mechanism includes a ring gear, a central gear, and a planetary gear. The central gear is coaxially arranged with the ring gear. The central gear and the planetary gear are located in the ring gear. The planetary gear is meshed between the ring gear and the central gear. The planetary gear rotates around its own axis and also around the axis of the central gear, so that the planetary gear can rotate relative to the central gear. The first air guide plate 210 may be connected to the central gear, and the second air guide plate 220 may be connected to the planetary gear. Not limited to this, other types of transmission mechanisms may also be used.

[0048] It should be noted that when the first air guide plate 210 and the second air guide plate 220 rotate at the same time, the angular velocity of the first air guide plate 210 and the angular velocity of the second air guide plate 220 are different. It can also be understood that when the first air guide plate 210 and the second air guide plate 220 rotate at the same time, the first air guide plate 210 will gradually deviate from or gradually approach the second air guide plate 220. It can also be understood that the second air guide plate 220 can rotate relative to the first air guide plate 210, or the first air guide plate 210 can rotate relative to the second air guide plate 220.

[0049] In some other embodiments, two driving devices may be arranged to respectively drive the first air guide plate 210 and the second air guide plate 220 to rotate. When the angular velocity of the first air guide plate 210 and the angular velocity of the second air guide plate 220 are different, the second air guide plate 220 can rotate relative to the first air guide plate 210, or the first air guide plate 210 can rotate relative to the second air guide plate 220.

[0050] Reference Figure 1 As shown, the air guide assembly 200 includes a louver assembly 230, and the louver assembly 230 includes a connecting rod mechanism 231 and a plurality of air guide blades 232. One side of the air guide blade 232 is an air inlet side, and the other side is an air outlet side. The air guiding direction of the air guide blade 232 is from the air inlet side toward the air outlet side. The connecting rod mechanism 231 extends along the length direction of the first air guide plate 210. It can also be understood that the connecting rod mechanism 231 extends along the left-right direction. The connecting rod mechanism 231 is slidingly connected to the first air guide plate 210. The connecting rod mechanism 231 can move along the length direction of the first air guide plate 210. The plurality of air guide blades 232 are arranged along the length direction of the connecting rod mechanism 231. The plurality of air guide blades 232 are respectively rotatably connected to the first air guide plate 210. The plurality of air guide blades 232 are respectively movably connected to the connecting rod mechanism 231, and specifically can be a rotatable connection. When the connecting rod mechanism 231 reciprocates along the length direction of the first air guide plate 210 , the connecting rod mechanism 231 drives the plurality of air guide blades 232 to swing back and forth simultaneously, thereby achieving left and right air sweeping.

[0051] It should be noted that in the related art, an additional driving device is usually used to drive the connecting rod mechanism 231 to move, such as a motor, so that the connecting rod mechanism 231 drives the multiple wind guide blades 232 to swing and realize the wind sweeping function, but this will result in higher manufacturing costs.

[0052] Based on this, for this embodiment, refer to Figure 1 and Figure 2As shown, the air guide assembly 200 also includes a linkage mechanism 240, which can be understood as being used to change the direction of force transmission. One end of the linkage mechanism 240 is connected to the second air guide plate 220, and the other end of the linkage mechanism 240 is connected to the connecting rod mechanism 231. When the first air guide plate 210 and the second air guide plate 220 rotate relative to each other, the first air guide plate 210 and the second air guide plate 220 will pull the linkage mechanism 240, so that the linkage mechanism 240 drives the connecting rod mechanism 231 to move along the length direction of the first air guide plate 210, and the connecting rod mechanism 231 drives the multiple air guide blades 232 to rotate simultaneously. It can also be understood that the connecting rod mechanism 231 drives the multiple air guide blades 232 to swing at the same time, and there is no need to set up an additional driving device to drive the air guide blades 232 to swing, which can save manufacturing costs. It can also be understood that the linkage mechanism 240 converts the circular motion of the second air guide plate 220 relative to the first air guide plate 210 into motion along the length direction of the air guide assembly 200, thereby changing the direction of force transmission.

[0053] The relative rotation of the first air guide plate 210 and the second air guide plate 220 is specifically explained below. It means that the first air guide plate 210 rotates relative to the second air guide plate 220, or the second air guide plate 220 rotates relative to the first air guide plate 210, which can also be understood as taking the first air guide plate 210 as a reference system, the position of the first air guide plate 210 remains unchanged, and the second air guide plate 220 moves relative to the first air guide plate 210, or taking the second air guide plate 220 as a reference system, the position of the second air guide plate 220 remains unchanged, and the first air guide plate 210 moves relative to the second air guide plate 220.

[0054] Alternatively, from another perspective, there are two situations in which the first air guide plate 210 and the second air guide plate 220 rotate relative to each other. The first situation is that the first air guide plate 210 gradually approaches the second air guide plate 220. The second situation is that the first air guide plate 210 gradually moves away from the second air guide plate 220. If the first air guide plate 210 and the second air guide plate 220 rotate synchronously, that is, the angular velocity of the first air guide plate 210 and the second air guide plate 220 are the same, the first air guide plate 210 and the second air guide plate 220 will not produce relative motion.

[0055] In some embodiments, the first air guide plate 210 and the second air guide plate 220 can rotate coaxially, that is, the rotation axis of the first air guide plate 210 coincides with the rotation axis of the second air guide plate 220. In some other embodiments, the first air guide plate 210 and the second air guide plate 220 can also rotate coaxially, that is, the rotation axis of the first air guide plate 210 and the rotation axis of the second air guide plate 220 are parallel to each other.

[0056] It should be noted that, in some embodiments, the first air guide plate 210 and the second air guide plate 220 rotate simultaneously, and the angular velocity of the second air guide plate 220 is greater than the angular velocity of the first air guide plate 210. Fig.12 As shown, in the shutdown state, the first air guide plate 210 and the second air guide plate 220 are closely attached to each other. Fig.13 As shown, in the power-on state, when the first air guide plate 210 and the second air guide plate 220 move toward Fig.13 After the second air guide plate 220 rotates in the rotation direction, since the angular velocity of the second air guide plate 220 is greater than the angular velocity of the first air guide plate 210, the second air guide plate 220 will rotate relative to the first air guide plate 210, and the position of the second air guide plate 220 will be ahead of the first air guide plate 210, and the second air guide plate 220 will be located above the first air guide plate 210. Fig.13 When the rotation direction of the air flow reciprocates, it can be understood that the first air guide plate 210 is sweeping the air up and down. At this time, the linkage mechanism 240 also drives the multiple air guide blades 232 to swing back and forth at the same time. It can be understood that the first air guide plate 210 and the air guide blades 232 are sweeping the air at the same time, and can sweep the air up and down as well as left and right, achieving the effect of linked air sweeping. The air sweeping effect is better, and the air outlet angle of the air outlet can be expanded, so that the air flow is diffused at a larger air outlet angle, and the cooling or heating effect is more uniform.

[0057] Reference Fig.13 As shown, in some embodiments, the first air guide plate 210 and the second air guide plate 220 are both arc-shaped plate structures. When viewed from the side, the arc length of the first air guide plate 210 is greater than the arc length of the second air guide plate 220, so that the surface area of ​​the first air guide plate 210 is larger, and the shutter assembly 230 can be easily installed, and the up and down wind sweeping is mainly achieved by rotating the first air guide plate 210 relative to the second air guide plate 220. In some other embodiments, the up and down wind sweeping can also be achieved by rotating the second air guide plate 220 relative to the first air guide plate 210. In some other embodiments, when viewed from the side, the contour line of the outer periphery of the first air guide plate 210 is a circular arc line, and the contour line of the outer periphery of the second air guide plate 220 is a circular arc line, and the radius of the two circular arc lines can be equal.

[0058] It is understandable that, referring to Figure 1 As shown, in some embodiments, the plurality of wind guide blades 232 are divided into a plurality of first blades 233 and a plurality of second blades 234, the plurality of first blades 233 are parallel to each other, and the plurality of second blades 234 are also parallel to each other. It can also be understood that the plurality of wind guide blades 232 are divided into a first group and a second group, wherein the wind guide blades 232 in the first group are the first blades 233, and the wind guide blades 232 in the second group are the second blades 234, and the first group and the second group are arranged on the left and the right, respectively.

[0059] Specifically, refer to Figure 1As shown, the link mechanism 231 includes a first rod 2311 and a second rod 2312, the first rod 2311 is slidably connected to the first air guide plate 210, the second rod 2312 is also slidably connected to the first air guide plate 210, the first rod 2311 and the second rod 2312 can slide along the length direction of the first air guide plate 210, the first rod 2311 is rotatably connected to the plurality of first blades 233, and the second rod 2312 is rotatably connected to the plurality of second blades 234. The linkage mechanism 240 connects the first rod 2311 and the second rod 2312 together.

[0060] When working, the linkage mechanism 240 can drive the first rod 2311 and the second rod 2312 to move. When the first air guide plate 210 and the second air guide plate 220 rotate relative to each other, the linkage mechanism 240 drives the first rod 2311 and the second rod 2312 to move closer to or farther from each other along the length direction of the first air guide plate 210, thereby driving the plurality of first blades 233 and the plurality of second blades 234 to rotate simultaneously, thereby achieving left and right wind sweeping. The linkage mechanism 240 mainly links the relative movement between the first air guide plate 210 and the second air guide plate 220 with the movement of the first rod 2311 and the second rod 2312.

[0061] It should be noted that, in this embodiment, by dividing the multiple air guide blades 232 into multiple first blades 233 and multiple second blades 234, the wind sweeping effect of the air guide blades 232 can be improved, so that the air guide blades 232 can cover the air outlet along the length direction of the first air guide plate 210 as much as possible, with a large coverage area, and the airflow flowing out of the air outlet can be guided more comprehensively. In addition, in this embodiment, the first rod 2311 and the second rod 2312 are arranged to respectively drive the multiple first blades 233 and the multiple second blades 234 to swing, so as to avoid one connecting rod driving all the air guide blades 232 to swing, reduce the load bearing of the connecting rod, and also reduce the movement resistance of the connecting rod mechanism 231, so that the movement is smoother.

[0062] In some embodiments, the plurality of air guide blades 232 may also be divided into multiple groups, and then connecting rod mechanisms 231 and linkage mechanisms 240 may be arranged corresponding to the multiple groups of air guide blades 232. For example, the plurality of air guide blades 232 may be divided into four groups, and then four connecting rods may be arranged correspondingly. Each connecting rod is rotatably connected to one group of air guide blades 232. There are two linkage mechanisms 240, one of which drives the first and second groups of air guide blades 232 to swing, and the other linkage mechanism 240 drives the third and fourth groups of air guide blades 232 to swing.

[0063] It is understood that in some embodiments, the shutter assembly 230 has an initial state and a wind sweeping state, referring to Figure 1 and Figure 6As shown, the air conditioner indoor unit 1000 is in the off state, the shutter assembly 230 is in the initial state, and the plurality of first blades 233 are parallel to the plurality of second blades 234. It can also be understood that the first blades 233 have a first wind guiding direction, the second blades 234 have a second wind guiding direction, and the first wind guiding direction of the first blades 233 is the same as the second wind guiding direction of the second blades 234. Figure 5 and Figure 7 As shown, when the air-conditioning indoor unit 1000 is on, the shutter assembly 230 is in a wind sweeping state, and from the air outlet side of the air guide blade 232 to the air inlet side of the air guide blade 232, the first blade 233 and the second blade 234 are inclined in directions away from each other. It can also be understood that the rear side of the air guide blade 232 is the air inlet side, and the front side of the air guide blade 232 is the air outlet side. From the front side to the rear side, the first blade 233 is inclined to the left, and the second blade 234 is inclined to the right. It can also be understood that the first air guiding direction of the first blade 233 is set along the left front, and the second air guiding direction of the second blade 234 is set along the right front, that is, air is discharged to the left and right sides.

[0064] Reference Figure 7 As shown, from another perspective, any one of the first blades 233 and any one of the second blades 234 are selected as references. In the length direction of the connecting rod mechanism 231, the distance between the first blade 233 and the corresponding position of the second blade 234 is d, and d gradually increases in the direction away from the air outlet. It can also be understood that the distance d gradually increases in the direction perpendicular to the connecting rod mechanism 231. In some embodiments, it can also be understood that the distance d gradually increases along the front side of the air conditioner indoor unit 1000, or it can be understood that the distance d gradually increases along the air outlet direction of the air conditioner indoor unit 1000. The first blade 233 is inclined relative to the second blade 234. When viewed from a top view, the first blade 233 and the second blade 234 form an eight-shaped structure. The airflow flowing out of the air outlet is guided by multiple first blades 233 and diffuses to the left. The airflow flowing out of the air outlet is guided by multiple second blades 234 and diffuses to the right. The air outlet angle or air outlet range can be increased to improve the wind sweeping effect. It should be noted that when the linkage mechanism 240 pulls the first rod 2311 and the second rod 2312 closer to each other, the louver assembly 230 will switch from the initial state to the wind sweeping state; when the linkage mechanism 240 pulls the first rod 2311 and the second rod 2312 away from each other, the louver assembly 230 will switch from the wind sweeping state to the initial state.

[0065] In some embodiments, it can also be that when the louver assembly 230 is in the initial state, along the length direction of the connecting rod mechanism 231, the distance d from the first blade 233 to the second blade 234 gradually decreases in the direction away from the air outlet. It can also be understood that, viewed from a top-down angle, the first blade 233 and the second blade 234 form an inverted figure eight shape. When the louver assembly 230 switches from the initial state to the wind sweeping state, at a certain position, multiple first blades 233 will be parallel to multiple second blades 234, so that the airflow at the air outlet can be blown out in a positive direction without deflecting to the left or right. Then, the louver assembly 230 continues to switch to the wind sweeping state, so that the distance d from the first blade 233 to the second blade 234 gradually increases in the direction away from the air outlet, that is, viewed from a top-down angle, the first blade 233 and the second blade 234 form a figure eight shape.

[0066] In some embodiments, the linkage mechanism 240 may include only one rocker arm, which is a rod-shaped structure, and the connecting rod mechanism 231 may be a single rod-shaped structure. The connecting rod mechanism 231 extends along the length direction of the first air guide plate 210. One end of the rocker arm is rotatably connected to the connecting rod mechanism 231, and the other end of the rocker arm is connected to the second air guide plate 220. When the first air guide plate 210 and the second air guide plate 220 rotate relative to each other, the first air guide plate 210 and the second air guide plate 220 will pull the rocker arm, so that the rocker arm pulls the connecting rod mechanism 231 to move along the length direction of the first air guide plate 210, and the connecting rod mechanism 231 will pull the multiple air guide blades 232 to rotate simultaneously. The function of the linkage mechanism 240 can also be achieved by using a single rocker arm and a single connecting rod mechanism 231. Specifically, a spring or a spring sheet for assisting the above-mentioned rocker arm in resetting may also be provided, one end of the spring or the spring sheet is connected to the connecting rod mechanism 231, and the other end is fixedly provided, and may be specifically fixedly connected to the first air guide plate 210. When the second air guide plate 220 drives the rocker arm to move, the rocker arm pulls the connecting rod mechanism 231 to move along the length direction of the first air guide plate 210. The connecting rod mechanism 231 will stretch the spring or spring sheet. The elastic force provided by the spring or spring sheet to the connecting rod mechanism 231 can help the connecting rod mechanism 231 to reset, thereby driving the rocker arm to reset and making the movement of the rocker arm smoother.

[0067] It is understandable that, referring to Figure 4 , Figure 8 and Fig.11As shown, in some embodiments, the linkage mechanism 240 includes a first rocker arm 241 and a second rocker arm 242. The first rocker arm 241 is a rod-shaped structure, and the second rocker arm 242 is also a rod-shaped structure. One end of the first rocker arm 241 is rotatably connected to one end of the second rocker arm 242, the other end of the first rocker arm 241 is rotatably connected to the first rod 2311, and the other end of the second rocker arm 242 is rotatably connected to the second rod 2312. The end of the first rocker arm 241 away from the first air guide plate 210 is connected to the second air guide plate 220. The first rocker arm 241 and the second rocker arm 242 can be expanded or folded, the first rocker arm 241 can pull the first rod 2311 to move, and the second rocker arm 242 can pull the second rod 2312 to move.

[0068] Reference Figure 4 , Figure 8 and Fig.11 As shown, from another perspective, it can also be understood that the first rocker arm 241, the second rocker arm 242, the first rod 2311 and the second rod 2312 form a triangular structure. An angle θ is formed between the first rocker arm 241 and the second rocker arm 242. When the first air guide plate 210 and the second air guide plate 220 rotate relative to each other, θ will gradually increase or decrease. Specifically, when the first air guide plate 210 and the second air guide plate 220 gradually move away from each other, it can be understood that the second air guide plate 220 pulls the rotation connection position of the first rocker arm 241 and the second rocker arm 242, so that θ gradually decreases, the first rocker arm 241 and the second rocker arm 242 gradually move closer or arch upwards, and because the first rod 2311 is pulled by the first rocker arm 241, and the second rod 2312 is pulled by the second rocker arm 242, the first rod 2311 and the second rod 2312 will gradually move closer to each other. When the first air guide plate 210 and the second air guide plate 220 gradually approach each other, it can be understood that the second air guide plate 220 presses the rotational connection position of the first rocker arm 241 and the second rocker arm 242, so that θ gradually increases, and the first rocker arm 241 and the second rocker arm 242 gradually expand or unfold downward, and pushed by the first rocker arm 241 and the second rocker arm 242, the first rod 2311 and the second rod 2312 gradually move away from each other.

[0069] It should be noted that, in this embodiment, the first rocker arm 241 is used to drive the first rod 2311 to move, and the second rocker arm 242 is used to drive the second rod 2312 to move. When the first air guide plate 210 and the second air guide plate 220 rotate relative to each other, the first rod 2311 can drive multiple first blades 233 to rotate at the same time, and the second rod 2312 drives multiple second blades 234 to rotate at the same time, so that the linkage wind sweeping effect is better. In addition, the first rocker arm 241 and the second rocker arm 242 are symmetrical structures to each other, and the first rod 2311 and the second rod 2312 are also symmetrical structures to each other, so that the movement of the first rocker arm 241 and the second rocker arm 242 is smoother and the movement resistance is smaller.

[0070] It should be noted that since the linkage mechanism 240 has an arched state and an extended state, when the linkage mechanism 240 is in the arched state, the louver assembly 230 is in the initial state, and when the linkage mechanism 240 is in the extended state, the louver assembly 230 is in the wind-sweeping state. It is possible to consider arranging a reset member to assist the linkage mechanism 240 in resetting from the extended state to the arched state, so as to ensure smooth movement of the linkage mechanism 240 and the louver assembly 230 can be smoothly reset from the wind-sweeping state to the initial state.

[0071] It is understandable that, referring to Figure 8 As shown, in some embodiments, the air guide assembly 200 includes an elastic reset member 250, which can be a spring or a spring sheet or other elastic structure, and the elastic reset member 250 connects the first rocker arm 241 and the second rocker arm 242. It can also be understood that one end of the elastic reset member 250 is connected to the first rocker arm 241, and the other end of the elastic reset member 250 is connected to the second rocker arm 242. The elastic reset member 250 is used to provide elastic force to the linkage mechanism 240, and the elastic force tightens the first rocker arm 241 and the second rocker arm 242, so that the first rocker arm 241 and the second rocker arm 242 have a tendency to gradually move closer or arch upwards. It can be understood that the elastic reset member 250 is used to assist the linkage mechanism 240 to return to the initial state, and ensure that the linkage mechanism 240 moves smoothly when it is reset. Specifically, when the angle θ between the first rocker arm 241 and the second rocker arm 242 gradually increases, the first rocker arm 241 and the second rocker arm 242 will further stretch the elastic return member 250, so that the elastic force of the elastic return member 250 gradually increases, which is more conducive to the elastic return member 250 assisting the linkage mechanism 240 in resetting. In addition, the elastic return member 250 can keep the linkage mechanism 240 in a centered position as much as possible after resetting, so that the multiple air guide blades 232 remain parallel to each other, ensuring that the air guiding direction of the air guide blades 232 will not deviate.

[0072] It should be noted that the elastic return member 250 can directly abut between the first rocker arm 241 and the second rocker arm 242, or a structure such as a buckle or hook connected to the end of the elastic return member 250 can be provided on the side where the first rocker arm 241 and the second rocker arm 242 are close to each other.

[0073] It is understandable that, referring to Figure 2 and Figure 8As shown, in some embodiments, the first air guide plate 210 has an inner surface and an outer surface, the inner surface of the first air guide plate 210 is provided with a guide seat 260, the guide seat 260 is located between the first rod 2311 and the second rod 2312, the guide seat 260 is provided with a first limiting groove 261, the first limiting groove 261 penetrates the guide seat 260 along the length direction of the first guide plate, so that a first opening portion 262 and a second opening portion 263 connected to the first limiting groove 261 are formed on both sides of the guide seat 260, respectively, and the first rod 2311 slides with the first limiting groove 261. The second rod 2312 is also slidably connected to the first limiting groove 261. Specifically, the first rod 2311 extends into the first limiting groove 261 from the first opening 262, and the second rod 2312 extends into the first limiting groove 261 from the second opening 263. The cross-sectional contour line of the first limiting groove 261 matches the cross-sectional contour lines of the first rod 2311 and the second rod 2312, thereby limiting the first rod 2311 and the second rod 2312 to slide only along the first limiting groove 261, playing a limiting role and preventing the first rod 2311 and the second rod 2312 from running off.

[0074] It is understandable that, referring to Figure 4 and Figure 8 As shown, in some embodiments, a third opening portion 264 connected to the first limiting groove 261 is provided on the side of the guide seat 260 away from the first air guide plate 210, and the third opening portion 264 extends along the length direction of the guide seat 260, and the length of the third opening portion 264 is smaller than the length of the first limiting groove 261, and one end of the first rocker arm 241 away from the second air guide plate 220 is passed through the third opening portion 264, and one end of the second rocker arm 242 away from the second air guide plate 220 is also passed through the third opening portion 264.

[0075] Specifically, when the linkage mechanism 240 is gradually unfolded to the limit position, the end of the first rocker arm 241 will abut against the side wall of the third opening 264 along the length direction, and the end of the second rocker arm 242 will abut against the side wall of the third opening 264 along the length direction, so that the linkage mechanism 240 cannot continue to unfold, thereby limiting the movement of the first rocker arm 241 and the movement of the second rocker arm 242, playing a limiting role, and preventing the linkage mechanism 240 from shaking or running off. It can also be understood that, due to the small length of the third opening 264, when the angle θ between the first rocker arm 241 and the second rocker arm 242 is too large, that is, the degree of unfolding of the linkage mechanism 240 is large, the first rocker arm 241 and the second rocker arm 242 will respectively abut against the side walls of the third opening 264 along the length direction, thereby limiting the range of movement of the first rocker arm 241 and the second rocker arm 242, preventing the linkage mechanism 240 from being too large in degree of unfolding, and protecting the air guide blade 232. At the same time, the third opening portion 264 also has an avoidance function, so that the first rocker arm 241 and the second rocker arm 242 can extend into the first limiting groove 261 to be rotatably connected with the first rod 2311 and the second rod 2312 .

[0076] In some other embodiments, the first rocker arm 241 and the second rocker arm 242 may be rotatably connected to the first rod 2311 and the second rod 2312 without extending into the first limiting groove 261, but the limiting effect on the first rocker arm 241 and the second rocker arm 242 is not as good as that of the present embodiment.

[0077] In some embodiments, the elastic return member 250 may not be arranged between the first rocker arm 241 and the second rocker arm 242. Along the length direction of the third opening portion 264, one side of the third opening portion 264 has a first side wall and the other side has a second side wall. The number of elastic return members 250 is two, one of which is connected between the first rocker arm 241 and the first side wall, and the other is connected between the second rocker arm 242 and the second side wall.

[0078] It is understandable that, referring to Figure 8 and Fig.11 As shown, in some embodiments, a rotating shaft portion 2412 is provided at one end of the first rocker arm 241 away from the second air guide plate 220, and a rotating shaft portion 2412 is also provided at one end of the second rocker arm 242 away from the second air guide plate 220. Figures 8 to 10As shown, the side wall of the first limiting groove 261 is provided with a second limiting groove 265, and the second limiting groove 265 is extended along the length direction of the first air guide plate 210. It can be understood that the second limiting groove 265 is formed by removing part of the side wall of the first limiting groove 261. The axis of the rotating shaft portion 2412 is perpendicular to the length direction of the second limiting groove 265, and the rotating shaft portion 2412 is slidably connected to the second limiting groove 265. When the first rocker arm 241 and the second rocker arm 242 are unfolded or retracted, the rotating shaft portion 2412 can rotate around its own axis, and the rotating shaft portion 2412 can also slide along the second limiting groove 265. The rotating shaft portion 2412 can be a cylindrical structure or a roughly cylindrical structure, which is relatively smooth and can rotate around its own axis.

[0079] In this embodiment, the rotating shaft portion 2412 and the second limiting groove 265 are mainly used to guide the first rocker arm 241 and the second rocker arm 242 along the length direction of the guide seat 260, which can improve the movement accuracy of the first rocker arm 241 and the second rocker arm 242 and prevent the first rocker arm 241 and the second rocker arm 242 from deviating.

[0080] It is understandable that, referring to Figure 2 and Figure 4 As shown, in some embodiments, the first air guide plate 210 is provided with a first connecting ear 211, the second air guide plate 220 is provided with a second connecting ear 221, the first connecting ear 211 is rotatably connected to the second connecting ear 221, the first rocker arm 241 is provided with a hook portion 2411, the second connecting ear 221 is provided with a bayonet portion 222, and the hook portion 2411 cooperates with the bayonet portion 222.

[0081] In this embodiment, by providing the structure of the hook portion 2411 and the bayonet portion 222, the assembly operation can be facilitated. When the second air guide plate 220 rotates relative to the first air guide plate 210, the first connecting ear 211 and the second connecting ear 221 will pull the first rocker arm 241 and the second rocker arm 242, thereby driving the connecting rod mechanism 231 to move. Specifically, the first connecting ear 211 and the second connecting ear 221 are located between the plurality of first blades 233 and the plurality of second blades 234, and it can also be understood that the first connecting ear 211 and the second connecting ear 221 are located between the first rod 2311 and the second rod 2312, and it can also be understood that the first connecting ear 211 and the second connecting ear 221 are located in the middle position of the first air guide plate 210, so that the first rocker arm 241 and the second rocker arm 242 can be kept in the middle position to prevent the wind guide direction of the wind guide blade 232 from deviating.

[0082] In addition, in some other embodiments, when the first air guide plate 210 and the second air guide plate 220 rotate relative to each other, since the hook portion 2411 may move relative to the bayonet portion 222, the hook portion 2411 can be set to an arc-shaped structure, such as a U-shaped structure, so that the hook portion 2411 can move relative to the bayonet portion 222, so that the movement of the first rocker arm 241 and the second rocker arm 242 is smoother, and the hook portion 2411 can be prevented from hindering the relative rotation of the first connecting ear 211 and the second connecting ear 221.

[0083] In some other embodiments, in addition to setting the structure of the hook portion 2411 and the bayonet portion 222, the first rocker arm 241 can also be directly and movably connected to the second connecting ear 221, for example, by cooperating between a slider and a guide rail, or by cooperating between an arc hole and a rotating shaft.

[0084] It should be noted that, for the above-mentioned embodiment, the rotational connection between the first connecting ear 211 and the second connecting ear 221 can be realized by adopting a structure of a rotating shaft and an axial hole, or by adopting other commonly used hinge structures.

[0085] It should be noted that the length directions of the above-mentioned air guide assembly 200, the first air guide plate 210, the second air guide plate 220 and the connecting rod mechanism 231 are the same. When the air-conditioning indoor unit 1000 is a wall-mounted air-conditioning indoor unit, the length direction is generally the left-right direction. When the air-conditioning indoor unit 1000 is a cabinet-type air-conditioning indoor unit, the length direction is generally the up-down direction.

[0086] The utility model further provides an air conditioner. Since the air conditioner includes the air conditioner indoor unit 1000 of the above embodiment, it has the above technical effects, which will not be described in detail herein.
